Build from SourceΒΆ

Install Robusta from source to develop new features for the Robusta Engine (robusta-runner).

To install Robusta as a user, follow Monitor Kubernetes from Scratch instead.

To develop new playbook actions, you don't need to install from source. Refer to Developing New Actions.

Using SkaffoldΒΆ

  1. git clone the source code.

  2. Install skaffold and helm

  3. Run helm repo add prometheus-community

  4. Run robusta gen-config and copy the result to deployment/generated_values.yaml

  5. Run skaffold run --tail. On M1 Macs, add -p apple-m1-dev

Common Errors

Occurs on Mac OS if dependencies are missing. Run brew install libjpeg.

Sometimes, when attaching a debugger to Robusta the following error occurs: NotADirectoryError: [Errno 20] Not a directory

If this occurs, disable the Attach to subprocess option on your debugger.

Want Faster Builds? ⚑️
  1. Install gcloud

  2. Run gcloud auth application-default login

  3. Build with skaffold run -p gcloud-build

Local DevelopmentΒΆ

When Using Skaffold, Robusta runs inside a Kubernetes cluster.

For faster code changes, you can run Robusta on your local computer:

  1. git clone the source code

  2. Run ./


You must have a cluster with Robusta installed for this to work. The runner needs a configuration file to run and it extracts it from your existing cluster.

Additional tips:

  • If you want to develop playbooks locally, configure playbookRepos with a local path to your playbooks directory.

  • Your local runner wont incoming Kubernetes changes or Prometheus alerts.

  • For instructions on simulating Prometheus alerts, try poetry run robusta playbooks trigger --dry-run prometheus_alert alert_name=KubePodCrashLooping namespace=default pod_name=example-pod

CLI DevelopmentΒΆ

To develop the robusta cli:

  1. git clone the source code

  2. poetry install

  3. poetry run robusta

Alternative method, using pip not poetry

Install the robusta cli into your global python environment:

  1. git clone the source code

  2. pip3 install .
